Running Phenix 1.5.2 with Martin Horvath
by Raghav Kalia 04 Nov '09

04 Nov '09

I recently downloaded and installed phenix 1.5-2. I can launch the GUI by double clicking on the phenix icon. However, I cannot get to run phenix.refine on the command line. How does one set paths so that phenix.refine will be recognized in a terminal window? Raghav Kalia

Elbow ligand building
by Joe Krahn 04 Nov '09

04 Nov '09

I am having some problems building ligand parameters with elbow. I have an accurate reference structure, but elbow seems to "regularize" the coordinates in a way the distorts the structure. Is there a way to disable this? With --opt, QM optimization should hopefully remove distortions, but it is not doing a very good job for this molecule. So, I decided to optimize using Gaussian, and a better basis set. It seems that the Gaussian interface is still fairly simple, and it seems that you have to edit the Gaussian.csh template. So, I did that, but got the "Gaussian does not seem to be installed" message. Unfortunately, elbow runs the Gaussian script with output to /dev/null, so there is no way to see any error messages. Maybe that should be done only when the --quiet flag is given. I edited the Python source to let errors go to the tty, and found that the problem is in the way the script is invoked using "csh -c %s.csh". That only works if "." is in your $PATH, which is often the case. It also invokes an extra instance of csh, because it is invoked as a system command. The correct way to run a shell script is to leave out the '-c'. Elbow makes the script executable, so an even better approach is to just leave out "csh", and do "os.system('./%s.csh' % project)". Then, the script can be in sh/bash/etc. Maybe the was the intent of using '-c'? Thanks, Joe Krahn

re-run jobs in GUI
by Leo Sazanov 04 Nov '09

04 Nov '09

Hi, in a new GUI how can one re-run previous jobs (to make some modifications to them)? If I just try to open parameter (.eff) file from the main file menu in Autobuild, the file does not show up, even though it exists. Just adding it to the list of input files works, but the information is not passed on into GUI? -- Dr. Leonid A.

low resolution, high B, low R
by gerwald jogl 03 Nov '09

03 Nov '09

Hi All, I am working on a 4.2 A structure and feel somewhat uneasy about my refinement results. First, my R/Rfree at the moment is 0.18/0.25. The refinement is not complete and weights are not optimized, so the gap may get smaller. It's just that at 4.2 A, I don't quite expect such low R factors... There is nothing funny with the data, no messing around, no conversions - straightforward data set and a basic rigid body, individual_sites+group_adps, simulated annealing, no tls yet, no ncs. I am aware that one possible answer is that phenix is just really good... The other issue is about B factors. Phenix will happily refine B factors to values of 300 if there is no density in the region and that brings up the question about how to deal with disordered regions in general. Are there any current opinions out there about what would constitute 'reasonable' B factors? Conversely, when would a B factor indicate that it is better to remove the residue from the model instead of leaving it and calling it disordered. Also, this is after group_adp at 4.2 A - should I maybe take this as an indication that this is asking too much from the data and go back to a single adp per chain and tls? All comments are appreciated. Thanks! Gerwald

You are right. It started in the 2nd macro cycle. I should have been a little more patient. Sorry about it.

Re: [phenixbb] optimization of wxc and wxu
by Xuewu Zhang 03 Nov '09

03 Nov '09

Hi phenix developers/gurus, I am using the latest night build of phenix on OS X snow leopard. I found that phenix ignores these lines in my custom refinement file: refinement.target_weights.optimize_wxc="True" refinement.target_weights.optimize_wxu="True" Manually setting up the scale factors however works. I am not sure whether this is a bug or a platform related issue. Thanks, Xuewu Zhang

GUI and X servers
by Leo Sazanov 02 Nov '09

02 Nov '09

Hi, I am accessing our linux server (where phenix sits) via Exceed X server from Windows machine, and everything used to work fine until recent (I think from v.1-5-2) versions of phenix. Now if I launch new GUI, mouse position is not recognised anymore not only by phenix, but then also by other programs - so if I click on something, something else completely gets activated. I did not change any Exceed settings, so the problem seems to be due to phenix. Also, same thing happens with Xming server. If I access from Mac machine, everything seems to be OK. Has anybody seen it and what could be the reason for that? Thanks! -- Dr. Leonid A.

Converting .mtz to xplor or having phenix output to xplor file
by Sam Stampfer 28 Oct '09

28 Oct '09

Hi, This isn't exactly phenix-related but someone might know an easy solution. I'm trying to open an electron density map in pymol. It won't open .mtz files and the .xplor files I generated from ccp4i don't seem to work either. I need to have my density as a .xplor file in order for pymol to open it (I think). How would I generate a .xplor file from .mtz? Or, alternately, how can I set phenix to output a .xplor file? I've had it output to a cns file instead of .mtz but that didn't help me get it in .xplor format. Thanks! -Sam
